You have been tasked with making Virtual Desktop Infrastructure (VDI) work in order to minimize the management of desktops. As you move VDI into production, you realize that the system resources required to support standard AV on these systems drops your number of concurrent users to an unacceptable level. You see potential for would-be users logging in, but being denied sessions due to lack of VDI resources. This bottleneck could occur with the arrival of a popular attachment or large file issued companywide, causing multiple users to access it at the same time, launching multiple AV scans. A performance hit is also caused by download and installation of required daily updates (DAT signatures and feature updates). When multiple systems update at once, the cumulative effect on the shared memory and processing of the host causes a spike in overall resources and can lead to a full system denial of access for new requests. With users relying on this new virtual desktop, denial of access is not an option, so you factor in additional resources and capacity, leading to a higher cost solution.
